Answer:
96 hours
Step-by-step explanation:
25 eyes - 2 hours
1200 eyes* - x hours
[tex]x = \frac{2 \times 1200}{25} [/tex]
[tex]x = 96[/tex]
*each student has 2 eyes. So 600 students have 600×2=1200 eyes.
It will take the nurse 48 hours to give eye tests to all 600 students in her school.
What is Expression?An expression is combination of variables, numbers and operators.
If the nurse can give 25 eye tests in two hours, then she can give 12.5 tests in one hour (since 25 divided by 2 equals 12.5).
To give eye tests to all 600 students, the nurse will need to give 600 tests in total.
Using the rate of 12.5 tests per hour, we can set up a proportion:
12.5 tests / 1 hour = 600 tests / x hours
Apply Cross-multiplication
12.5 tests × x hours = 600 tests
Divide both sides by 12.5 tests
we get, x hours = 600 tests / 12.5 tests per hour
x hours = 48 hours
Therefore, it will take the nurse 48 hours to give eye tests to all 600 students in her school.

Answer: 32/9

Step-by-step explanation:
Answer:
9x - 24 = 8 (D)
Step-by-step explanation:
3/4x - 2 = 2/3
Find ways to get each number (for example the 9x in 9x - 2 = 8) using the 3/4x
If we’re using 9x - 2 as the example, you find how many 3/4s fit into 9, which is 12
So the scale factor is 12.
You do 3/4*12 for 9 and see if it also fits with the -2
-2*12 = -24
You know that that one is wrong.
But if you look, there is an equation that has 9x and -24, so the third one is the answer
(Had I not been lucky enough to find those numbers before, you would’ve just done the same steps with the other problems)
Hope this helps! Good day ^_^
Heyyy! What is 0.45 (5 repeating) as a fraction?
Answer:
41/90
Step-by-step explanation:
- The answer given above does not actually have the repeating 5, this fraction does:
x = 0.455555
100x = 45.55555
10x = 4.5555555
90x = 41 (rounded)
therefore, the fraction is 41/90

Gina Needs To Pack 130 Pens, 50 Pencils And 20 Erasers Into Identical Gift Bags So That Each Item Is Equally Distributed Among The Gift Bags. (I) Find The Largest Number Of Gift Bags That Can Be Packed. (Ii) Find The Number Of Each Item In A Gift Bag.
Answer:
Step-by-step explanation:
I think the best way is to split up the erasers before you do anything. That would mean there were 20 gift bags in all
If you did that, then each gift bag would contain 2 pencils with 10 left over.
Further 130 pens would divide up into 6 pens in each gift bag with 10 pens left over.

Step-by-step explanation:
The bill given after the voucher was used was 36.72.
If we multiply 36.72 with the voucher amount of 15% or .15
36.72*.15=5.508
We then have to add 5.508 to 36.72.
36.72+5.508=42.228=42.23 when rounding up.

Answer:
11·11^4
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
a = a^1
(a^b)/(a^c) = a^(b-c)
a^0 = 1 . . . . for any 'a' not 0
__
The given expression is ...
(11^8)/(11^3) = 11^(8-3) = 11^5
The offered choices are ...
(11^7)/(11^7) = 11^(7-7) = 11^0 = 1
11·11^4 = (11^1)(11^4) = 11^(1+4) = 11^5 . . . . matches the given expression
(11^0)/(11^5) = 11^(0-5) = 11^-5
11^0 = 1
A tuxedo shop rents its tuxedos for $30 per day. They charge a nonrefundable fee of $ 60 for each tuxedo.
Use the dropdown boxes to create an equation that could be used to determine the total cost, y of renting a tuxedo for x days.
Given parameters:
Charge per day of Tuxedo = $30 per day
Non-refundable charge = $60 for each tuxedo
Unknown:
Equation to determine total cost = ?
Solution:
Represent;
Total cost = y
Number of days = x
Now;
Total cost = Non refundable charge + charge per day
y = $60 + $30x
The equation is;
y = 60 + 30x for a tuxedo

The distance, d, that a certain car is from Math City after h hours, can be determined by the equation d=45h. The distance that a second car is from Math City can be determined by the equation d=25h+80. After how many hours will the two cars be the same distance from the Math City?
Answer:
4 hours
Step-by-step explanation:
First car distance
d = 45h
Second car distance
d = 25h + 80
After how many hours will the two cars be the same distance from the Math City?
Equate both car's distances
45h = 25h + 80
Collect like terms
45h - 25h = 80
20h = 80
Divide both sides by 20
h = 80 / 20
= 4
h = 4 hours
The two cars will be at the same distance from the Math City in 4 hours
